COMBINED FAUCET AND BEER=PUMP.

SPECIFICATION forming part of Letters-Patent No. 339,295, dated April 6, 1886.

Application filed January 11, 1886.

.To all whom, t may concern:

Be it known that I, EMIL M. HUGENTOBLER, a resident of the city, county, and State of New York, have invented a new and Improved Combined Beer Pump and Faucet, of

which the 'following is a complete description, reference being had to the accompanying drawings, forming part of this specieation.

My invention relates to hand-pumps which lo are used for forcing air into a barrel of beer while on tap, and which are so construct-ed that the same motion which operates the pump also opens the faucet through which the beer` is dispensed, and more particularly to such of i 5 these hand-pumps as are used in connection with or attached to a refrigerator in which the beer is kept; and the object of my invention is to provide certain new and novel details of mechanism in the construction of said pumps, 2o whereby they may be attached to the refrigerator in an easier and more practical manner than heretofore, and also whereby the operation of the pump to force air into the barrel may be made at will independent of the open- 2 5 ing` of the beer-faucet.

In the accompanying drawings, (in which corresponding parts are designated by similar letters of rei'erence,) Figure l represents a vertical erosssection of my improved combined beer pump and faucet on line A B of Fig. 3. Fig. 2 represents a cross-section at line O D of Fig. l. Fig. 3 is an end View in vertical elevation. Fig. 4 shows a rear elevation of the back head of the pump cylin- 3 5 der, and Fig. 5 represents a washer placed on the end of the plug-cock of the faucet.

In the drawings', l? represents a single-act ing air-pump, the working end (to the left) being provided with an inlet-valve, t', and an 40 outlet-valve, o, the former in the shape of an ordinary puppet-valve, held to its seat by a spring, and the latter in the shape ofa nipple of rubber resembling a thimble split across its end and fitting over a teat of metal,

to which it is fast, and through which the air flows from the pump. The valves i and o are located in the back head H of the pump, and this head is drawn up to the barrel F by means of two (or more) bolts, 7l. lz., running 5o through lugs or ears on said back head H and Serial No. 188,102. (No model.)

on the front head H', the joint between the back head H (on the working end) and the pump-barrel F being, of course, a tight one.

A piston, p, of suitable construction, is fitted into the barrel F, and is attached to a pitman 5 5 or connecting rod, It, the other end of which is attached to a lever, L, by means of a pin or bolt, '1'. The front head II of the pump P carries in its center a threaded socl;et,which fits over the threaded end of the tube t, so as 6o to bring the pump inline with said tube t and secure it in that position. The tube t is con centric with and forms part of the main body of my machine-the piece T. This piece is composed of a straight round part Acored throughout its length, and having a flange or head, S, and beyond this iiange a spout or spigot, V, slanting off at au angle and provided with a taper plug or cock, K. The core in the spout V is connected to the core 7o in the straight part of the main body T. The tube t is slipped through the straight part of the piece T, being made concentric therewith, and is fastened at both ends to the ends of said straight part either by threads or by sol- 7 5 dering, or in any manner which will insure a permanent and tightjoint; or, if desired, the tube t may be cast in the core ot' the piece T, although practical considerations obviousl y make it preferable to form the two pieces separate and tit them together.

At the point U on the end of the piece T, opposite the i'lange S, a hole is drilledinto and at right angles to the piece T, but not, however, through the tube t. Into this hole is tapped a nipple, N, of suitable shape, and itbecomes evident that a communication is thus made between the nipple Naud the cock K through the annular core between T and 1:, and through the spout V, while at the same time the presence of this tube t in the center ofthe straight part of the piece T (to both ends oi' which it is permanently secured) makes ol' this piece T practically a tube open at both ends. At the end opposite the liange S the tube t is al- 95 lowed to project beyond the piece T, and it is this project-ing end which engages into the threaded socket previously described on the front head II of the pump I), this joint so formed, not requiring to be air or water tight, 10c

as it is simply intended to hold the pump barrel in position. The lever L isfulerumedon the shank of the cock K, the axis of ywhich latter is located below the eenterof the pump l? and at right angles thereto. The connect ing-rod R plays through the tube t, which is of sufficient diameter to permit the rod to vibrate up and down as its outer end swings with the lever L. The shankf of the cock K is shown here in the shape of a round stem, cast with the cock, and on this stem fits the eye of the lever L, so that the swing of the lever is concentric with that of the cock.

XV is a washer pinned on the end of the shankf outside ofthe lever L, which it serves thereby to secure in position. This washer carries a notch, n, on its periphery, and the washer is secured so as to turn with the cock K'. On the lever Lis hinged in asuitable slot and on a pin, a, perpendicular to the axis of the cock K, a small piece or latch, b. Aspring, c, and a projection, d, on the latch, will secure the latter either up or down, as reference to the drawings will show without any further explanation. VVhen the latch I) is down, as shown by the full lines in the drawings, it engages in the notch a on the washer "W, and therefore every motion of the lever L carries the cock K with it, whereas, when the latch b is up-viz., in the position shown by the dot ted lines-the lever L may be moved on the shank of the cock K as a fulcrum without said cock being moved at all. The straight part of the piece T is threaded for a portion of its length, beginning from the pump end, and on this thread is engaged a nut, M, preceded by the washer m.

G represents the wall of the ice box or refrigerator to which the apparatus is attached, and wherein the beer-barrel is kept, and the pump is located inside the ice-box, while the spout Y, cock K, and lever L are on the outside. A flexible hose or pipe, X, is attached to the nipple N, and its other end is attached to a bung driven into the barrel. A hose or flexible pipe, Y, is attached to a suitable fitting on the back head of the pump, so as to carry the air from the valve o to the barrel, the other end of the hose Y being attached to an air-vent or air-bung driven into the barrel. It follows that every stroke of the lever L and pump l? will force a certain amount of air in the barrel, and will or will not, according to the position of the latch b, simultaneously open the cock K and allow a certain amount of beer to run out.

In the use of combined beer pumps and faucets a great desideratum is to cut as f'ew holes as possible through the walls of the refrigerator, and to keep such holes closed tightly, so that the cold air cannot escape. Another important requirement is to make the adjustment of the different parts of the machine, as near as possible. independent of the difference in the thicknesses of refrigeratorwalls. Reference to the drawings shows at once that these requirements are met in my improved combined beer pump and faucet. To attach it to the refrigerator G, a suitable hole having been bored through the wall, the pin fr is removed, the pump is unscrewed bodily from the end of the tube t, and the nipple N is likewise unscrewed. The nut M and washer m being removed, the straight part of the body T is shoved through the hole in the wall G from the outside until the flange S bears against the wall, the washer m and nut M are put on from the inside, and the latter screwed home, there being thread enough on the piece T to make up for the thinnest walls met with in practice. Vhen the nut M is home, the washer m and the flange S practically close up the ice-box again and make the escape of cold air therefrom impossible. The pump is then screwed on again, the pin a is putin place, the nipple N is screwed in place, the flexible tubes X and Y are attached, and the machine is ready for operation.

It becomes apparent that the requirements above mentioned are met without it being necessary to make any special adjustment of the parts beyond that of the nut M and washer m.

By the mode of construction described l am also enabled to take the pump off bodily.

An objection to the use of combined beer pumps and faucets lies in the fact that, as the pump must necessarily be of small capacity to be susceptible of easy operation, itis inadequate to force out at the faucet, especially when the level in the barrel gets low, more than a glass of beer at each stroke of the lever, it requiring several strokes to draw aquart, or even a pint; and where the beer-barrel lies in the cellar and it is desired to force the beer up to a cooling-coil in the ice-box on the floor above (where the pump and faucet are) this form of apparatus becomes worthless, from the fact that, as those heretofore constructed open the faucet and force out beer at each and every stroke, no air-pressure can be reached and stored in the beer-barrel sufficient to force any large amount at one stroke or to any great height. Vith this in view, I have devised the pump and faucet described above, wherein the action of the lever actuating the pump may or may not aetuate the cock, at the will of the operator. By this means a number of strokes may be given without opening the cock K, and therefore any required pressure of air may be reached and stored in the beerbarrel, or even,A if desired, in a separate airtank connected therewith.

Vhat I claim as my invention, and desire to secure by 4Letters Patent, is-

l. In a combined beer pump and faucet to be used in connection with an ice-box the wall of which is perforated with a single round hole through which the apparatus is secured, the faucet-body composed of a cylindrical straight part, T, tapped at one end at U to receive the nipple N, of an offset-spout, V, carrying the cock K, and of a straight tube, t, in the core of the straight part of the faucet-body and concentric therewith, all substantially as and for the purpose set forth.

2. In a combined beer pump and faucet to be used in connection with an ice-box the wall of which is perforated with a single round hole through which the apparatus is secured, the combination, with the faucet-body constructed as described, flange S, nut M, Washer m, and detachable nipple N, of the bodily-detachable air-pump l), set in line with and secured to said faucet-body, all snbstanti all y as described.

3. In a combined beer pump and faucet to be used in connection with an ice-box the Wall of which is perforated with a single round hole through which the apparatus is secured, the combinatiomwith the faucet-body constructed as described, of a singleacting air pump, P, attached to and in line with said faucet-body, the connecting-rod R, running through the tube t, and the lever L, to operate said pump, said lever being pivoted on the shank f of the cock K on the offset part or spout V of the faucetbody, substantially as and for thc purpose specified. 2 5

4. In a combined beer pump and faucet, the combination, with the lever L, operating an air-pump, P, and pivoted on the shank f of the cock K, of the Washer XV, permanently secured to the shank f, the notch u on the pe- 3o riphery of said Washer XV, the latch b,pivoted on the pin (t, and having the projection d bearing on the spring c, all connected and operated in such a manner that the lever L, While remaining at all times pivoted on the shank f 35 of the cock K, may at will be caused to operate said cock or to swing independentlyr of it, substantially as and for the purpose set forth.
